In the context of pediatric physical exercise, the analysis of factors affecting postural control (PC) provides insight into the development of sport-specific motor skills. This study aims to evaluate the static PC during single-leg stance in endurance, team and combat athletes from the Spanish National Sport Technification Program. A total of 29 boys and 32 girls, aged 12 to 16 years old, were recruited. Centre of pressure (CoP) was measured on a force platform in standing position for 40 s under two sensorial and leg dominance conditions. Girls showed lower MVeloc ( < 0.001), MFreq ( > 0.001) and Sway ( < 0.001) values than boys in both sensorial conditions (open and closed eyes). The highest values in all PC variables were observed with eyes closed in both genders ( < 0.001). Sway values were lower in boys combat-athletes compared to endurance athletes in two sensorial conditions and with non-dominant leg ( < 0.05). Young athletes in their teens enrolled in a Sport Technification Program have shown differences in PC when comparing different visual conditions, sport disciplines and gender. This study opens a window to a better understanding of the determinants of PC during single-leg stance as a critical element in the sport specialization of young athletes.
在儿科体育锻炼的背景下，对影响姿势控制（PC）的因素进行分析，可以深入了解特定运动技能的发展。本研究旨在评估西班牙国家体育技术化计划中耐力、团队和格斗运动员单腿站立时的静态 PC。共招募了 29 名男孩和 32 名女孩，年龄在 12 至 16 岁之间。在两种感觉和腿部优势条件下，使用力平台在站立位置上测量 40 秒的中心压力（CoP）。在两种感觉条件（睁眼和闭眼）下，女孩的 MVeloc（<0.001）、MFreq（>0.001）和 Sway（<0.001）值均低于男孩。在所有 PC 变量中，两性的闭眼时值最高（<0.001）。在两种感觉条件和非优势腿下，男孩格斗运动员的 Sway 值低于耐力运动员（<0.05）。参加体育技术化计划的十几岁的年轻运动员在比较不同视觉条件、运动项目和性别时，PC 存在差异。这项研究为更好地理解单腿站立时 PC 的决定因素提供了一个窗口，PC 是年轻运动员运动专业化的关键因素。
